また、本実施形態では、得られたナノ結晶合金薄帯を（好ましくは室温まで）冷却することが好ましい。
また、本実施形態は、得られたナノ結晶合金薄帯（好ましくは上記冷却後のナノ結晶合金薄帯）を巻き取ることにより、ナノ結晶合金薄帯の巻回体を得ることを含んでもよい。
Examples of the material of the heat transfer medium include copper, copper alloys (bronze, brass, etc.), aluminum, iron, iron alloys (stainless steel, etc.) and the like. Of these, copper, copper alloy, or aluminum is preferable because of its high thermal conductivity (heat transfer coefficient).

Further, the present embodiment may include winding the obtained nanocrystal alloy strip (preferably the above-cooled nanocrystal alloy strip) to obtain a wound body of the nanocrystal alloy strip. ..
なお、本実施形態では、非晶質合金薄帯で構成されたロール状の巻回体から非晶質合金薄帯を巻き出し、その非晶質合金薄帯に張力を加えながら、非晶質合金薄帯を走行させ、その走行する非晶質合金薄帯を伝熱媒体に接触させて加熱し、その加熱による熱処理によりナノ結晶化し、ナノ結晶合金薄帯を得て、そのナノ結晶合金薄帯をロール状の巻回体に巻き取る、連続ラインを設けてナノ結晶合金薄帯を作製することもできる。 In the present embodiment, the amorphous alloy strip is unwound from a roll-shaped winding body composed of the amorphous alloy strip, and the amorphous alloy strip is subjected to tension while being amorphous. The quality alloy strip is run, the running amorphous alloy strip is brought into contact with a heat transfer medium and heated, and nanocrystallized by heat treatment by the heating to obtain a nanocrystal alloy strip, and the nanocrystal alloy is obtained.

ナノ結晶合金薄帯は、ナノ結晶合金薄帯を樹脂フィルムに保持した状態でローラー等の部材で加圧するなどして外力を加えるクラック処理を施すことができる。これにより、ナノ結晶合金薄帯を定形、あるいは不定形に複数の個片に分割しても構わない。この場合、クラック処理されたナノ結晶合金薄帯の個片等が樹脂フィルムから脱落しない様に、クラック処理されたナノ結晶合金薄帯を他の樹脂フィルムや接着層等の被覆層で覆って、挟み込むのが好ましい。ナノ結晶合金薄帯は、脆化し加圧によって比較的容易にクラックを生じさせることが出来るものの、従来は透磁率を十分に低下させることができなかった。しかし本開示では、張力を付与した状態でナノ結晶化の熱処理を行ったナノ結晶合金薄帯を用いており、このナノ結晶合金薄帯は透磁率が小さいため、１２８ｋＨｚでの交流比透磁率μｒを１００以上２０００以下の範囲に簡易に調整できる。本開示におけるクラックとは、合金薄帯に形成される磁気的なギャップを指し、例えば、合金薄帯の割れ及び／又はひびが包含される。 The nanocrystal alloy strip can be cracked by applying an external force by pressing the nanocrystal alloy strip with a member such as a roller while holding the nanocrystal alloy strip on the resin film. Thereby, the nanocrystal alloy strip may be divided into a plurality of pieces in a fixed shape or an irregular shape. In this case, the cracked nanocrystalline alloy strip is covered with a coating layer such as another resin film or an adhesive layer so that the cracked nanocrystalline alloy strips do not fall off from the resin film. It is preferable to sandwich it. Although the nanocrystal alloy strip is brittle and can be cracked relatively easily by pressurization, the magnetic permeability has not been sufficiently reduced in the past. However, in the present disclosure, a nanocrystal alloy strip that has been heat-treated for nanocrystallization under tension is used, and since this nanocrystal alloy strip has a small magnetic permeability , the AC specific magnetic permeability at 128 kHz μr. Can be easily adjusted to the range of 100 or more and 2000 or less. The crack in the present disclosure refers to a magnetic gap formed in the alloy strip, including, for example, cracks and / or cracks in the alloy strip.
